Having worked with VALHALLA on numerous tracks recently, I can easily confirm that I cannot fault his work at all. His understanding of what I'm looking for from the process is 2nd to none.
The turnaround is always on point and the aftercare puts your mind at ease. Anytime I've not been comfy with a certain element of any track, our man James fixes the issue almost immediately, at no extra cost, making for both an enjoyable process and a phenomenal outcome time and time again.
It doesn't stop there, I've even told the lad he needs to up his prices, his output and his fees don't match up at all, the service our man provides for the money he's charging is just ridiculous. I'd highly recommend him to any producer out there, established or up and coming. Not to mention, he's a good C@nt as well, which always helps :)
